9 Claims. (01. 250-275) This invention relates to mountings forelectrical devices and more particularly to cushion type mountings forsupporting electron discharge and similar devices in a horizontal posi-5 tion from a vertical support or panel.

Cushion type mountings for electron discharge devices and the likeusually comprise, in general, a base or support portion, a socket, andresilient members supporting the socket from the base or supportportion. When such mountings are used for supporting an electrondischarge device or the like in a horizontal position, the stresses inthe resilient members are excessive so that undesirable tilting of thesocket member and un- 15 satisfactory cushioning of the device results.

One object of this invention is to prevent excessive stressing of theresilient members in cushion type mountings for supporting electrondischarge devices and the like in a horizontal 20 position on a verticalsupport or panel.

In one embodiment illustrative of this inven-, tion, a mountingcomprises a base adapted to be secured to a vertical support or panel, asocket having a plurality of horizontal apertures for receiving terminalprongs on the device to be supported, and a plurality of resilientmembers supporting the socket from the base.

In accordance with a feature of this invention, an auxiliary resilientsupport is provided on the base member and adapted to engage the deviceto be supported whereby the stresses in the resilient supporting membersare reduced. The auxiliary support may be in the form of a hanger havinga supporting portion secured to the base 35 of the mounting, a cradleportion in which the electron discharge or other device may rest, andcoiled springs connecting the cradle and supporting portion.

The invention and the various features thereof will be understood moreclearly and fully from the following detailed description with referenceto the accompanying drawings, in which:

Fig. 1 is a perspective view of a mounting constructed in accordancewith this invention mounted on a vertical panel, with a portion of anelectron discharge device supported by the mounting shown in dottedoutline;

Fig. 2 is a front view partly in section of the mounting shown in Fig. 1with the auxiliary support omitted;

Fig. 3 is a side elevational view of the mounting shown in Fig. 1,partly in cross-section along the line 33 of Fig. 2;

Fig. 4 is an enlarged detail perspective view of one of the terminal andcontact members embodied in the mounting shown in Figs. 1 to 3;

Fig. 5 is another enlarged detail perspective view illustrating amodification of the terminal and contact member shown in Fig. 4; and

Figs. 6 and 7 are perspective views of modifications of the auxiliarysupport shown in Figs. 1 and 2.

Referring now to the drawings, the mounting shown in Figs. 1 to 3,inclusive, comprises-a base or support portion including twosubstantially square similar base or support members l and II, which maybe of insulating material, such as a phenolic condensation product,secured together by a plurality of eyelets I2 and forming a centralrecess l3. Disposed within the recess is and spaced from the inner wallsof the members l0 and l l is a socket member, which also may be of aninsulating material, such as a phenolic condensation product, and whichincludes a body portion [4 and a base plate l secured to the bodyportion I4 by a central eyelet [6. The body portion [4 is provided witha plurality of apertures [1 for receiving the terminal prongs of anelectron discharge device, or the like, and is provided alsowith aplurality of recesses 8 disposed one below-and in communication witheach of the apertures H.

The socket member is resiliently supported within the recess l3 by aplurality of metallic members which may be, for example, of phosphorbronze, each of which, as shown clearly in Fig. 4, comprises a terminalportion I 9, a U-shaped contact portion 20, and an intermediateresilient portion 2|. Each terminal portion I9 is substantially L-shapedand is held between two plate members 22 and 23, which may be ofinsulating material, such as a phenolic condensation product, secured tothe supportmember II by the eyelets l2. Each of the contact portions 20,as shown clearlyin Fig. 2, is disposed in one of the recesses l8, beingpositioned longitudinally by the top of the body portion l4 and theplate l5, and has parallel arm portions 24 frictionally held in slots orgrooves 25 in the body portion I5. Each contact portion 20 is providedalso with integral projections 26 which abut against the inner wall ofthe body portion l5 and with guide lips 21 which are in axial alignmentwith the corresponding aperture ll.

As shown in Fig. 5, the intermediate portion of.

tioned in an aperture 15 in the wall or panel by bolts 3| which extendthrough the eyelets l3. If a device, such as an electron dischargedevice 32, is carried by the socket l4, l5, because of the weight of thedevice, the socket may contact with the support members l0 and I I sothat the device will not be supported resiliently and the electrodesthereof will not be protected against shocks and jars. Furthermore, theresilient portions 2| may be subjected to excessive stresses so thatthey may acquire a permanent set and the resiliency thereof may bematerially decreased.

In accordance with this invention, the aforementioned difficulties areovercome by providing an auxiliary resilient support which carries alarge part of the weight of the device 32 and holds it in such positionthat the socket member is maintained out of contact with the supportmembers l0 and I.

In one illustrative embodiment shown in Figs. 1 and 3, the auxiliarysupport comprises a pair of resilient arms 33 which may be of sheetmetal, each secured to the wall or panel by one of the bolts 3i andhaving an integral bent bracket portion 34 extending into the aperture15 and engaging the wall or panel to firmly position the arms 33. Aflexible strip 35 of fabric or similar material passes around extensions36 on the arms 33 and is adapted to be engaged by the device 32.Preferably, the arms 33 and strip 35 are so formed that when the device32 is in position, the longitudinal axis of the device 32 is at rightangles to the plane of the panel or wall 30. It will be apparent, then,that the device 32 is fioatingly supported by the auxiliary support andthe resilient portions 2| without excessive stressing of the resilientportions 2|.

In another illustrative embodiment shown in Fig. 6, the auxiliarysupport comprises a U- shaped frame member 31 which may be formed of awire rod, provided with arcuate portions 36 adapted to be engaged by theheads of securing members such as the bolts 3| for mounting theauxiliary support on the vertical wall or panel 30. The auxiliarysupport shown in Fig. 6 includes also another frame member which alsomay be formed of a wire rod, having arms 39 secured to the frame member31 as by welding, a hanger portion 40 adapted to engage the device 32,and resilient loop portions 4|.

In still another embodiment shown in Fig. '7, the auxiliary supportcomprises a U-shaped member 42 which may be formed of a wire rod, havingparallel forwardly extending arms 43 to which a strip 44 of fabric orthe like is suitably secured, the strip 44 being adapted to engage thedevice 32. The U -shaped member has secured thereto, as by welding,metallic washers 45 for receiving the bolts 3| or the like forsecuringthe auxiliary support to the vertical wall or panel 3|].

Although specific embodiments of this invention have been shown anddescribed, it will be understood, of course, that modifications may bemade therein without departing from the scope and spirit of thisinvention as defined in the appended claims.
